Abstract
A retractable cover system for a tipper trailer body (11) of a truck includes a cover (30) for the top of the trailer body (11), and a winder pulley (52) for controlling the movement of the cover (30) across the top of the trailer body (11). An endless cable (53) which connects to the cover (30), has its movement controlled by the winder pulley (52) and a plurality of support pulleys (44, 45, 46, 47, 48, 59, 60) also support the movement of the endless cable (53). The arrangement of the support pulleys (44 to 48, 59, 60) and endless cable (53) is such that by operation of the winder pulley (52), the cover is retractably moved over the top of the trailer body (11).
Claims2
A retractable cover system for a tipper trailer body of a truck, said retractable cover system comprising:
- (a) a cover for the top of the trailer body,
- (b) a plurality of movable bows connected to said cover, each movable bow having a guide at each of its opposed ends,
- (c) a pair of open channel tracks mounted on opposed side walls of the trailer body, each of said guides contacting an upper surface of one of said open channels,
- (d) an endless linear means for moving said cover which is connected to opposed side portions of the cover,
- (e) a first rotatable means for controlling the horizontal movement of said cover through Said linear means,
- (f) a plurality of second rotatable means for supporting said linear means,
- (g) a mounting assembly for mounting said first rotatable means to a front wall of said trailer body, and
- (h) a means for adjusting tension of said linear means, said means for adjusting tension being located on said mounting assembly,
- whereby the said endless linear means extends continuously between all the second rotatable means and said first rotatable means,
- the arrangement of the plurality of second rotatable means and endless linear means being such that the operation of the first rotatable means causes the simultaneous movement of the opposed side portions of the cover to retractably move the cover over the top of the trailer body.
